Green Day had most fun making new albums

Green Day have revealed the highlight of their careers so far has been producing their three new records '¡Uno!', '¡Dos!', '¡Tre!' and frontman Billie Joe Armstrong said they've never had so much fun

Green Day had the "funnest time" recording their new albums.

The 'American Idiot' rockers are releasing three records between September and January 2013 - '¡Uno!', '¡Dos!', '¡Tre!' - and frontman Billie Joe Armstrong says making them has been the highlight of the band's career so far.

He said: "These past few months have been probably the funnest time we've ever had."

He also added the band knew they had to start a new chapter in their career after finishing their 'American Idiot' musical last year.

He added to NME magazine: "The end of that era. After that we knew we had to start pounding the songs out again like it was the first time we'd ever been in a band. So that's what we did - just the three of us and Jason [White, long-term second guitarist] with a small set-up.

"Suddenly it felt so good to be doing it that way again. It just felt natural - and it ended up being weirdly fun."

The band - Billie Joe, drummer Tre Cool and bassist Mike Dirnt - are planning to play a huge tour to support their new albums and they performed an impromptu gig at the Reading festival last weekend, which was hailed by many as the highlight of the event.

The mayhem began after Billie Joe tweeted confirming the band were playing at 11am on Saturday (25.08.12) and thousands of eager fans rushed to see them, causing the tent to be closed.

Speaking about the gig he said: "They were afraid of chaos, basically - too many people outside the tent. But we worked it out. I mean, it's always fun when you're doing something you're not supposed to be doing, right?"
